I recently ran a large data recovery of photos on a RAID5 NAS (around 10,000 Canon CR2 RAW files), and it seems to have recovered a majority of the data, but the files are a smaller size and lower resolution (2560x1707). These are usually ~24MB, 21MP images. Is this expected? I can certainly work with 4.4MP images since I would otherwise have nothing, but I am just curious about why and if there is something I scanned incorrectly.

I've seen cases where an embedded thumbnail inside the file caused it to think it was at the end and truncated the file sizes. Try disabling the *.jpg extension and do the scan again for just CR2 files alone. Usually, that can solve it. If not, you'd just have to create a custom file type for the CR2 format.
